Paddlepig, its kinda like an unwritten law, or internet/forum etiquette that a surfer is fairly discrete about certain sessions. Yes, even if its a metro location.
One can still get an uncrowded metro wave from time to time if you're in the know... even if its only 30mins before the masses find out. That 30mins can be worth 3-4 hours in a crowd.
Im at the point now where I now never say anything about a good session except in face to face dialogue with a friend.
There are no secrets anymore, everyone knows that...but there are still possibilities for an uncrowded surf and I'll go the extra yard to get one.
If someone wants to spell out their sesh...well, thats up to them. If someone wants to be discrete about it, where ever it may be...they have the right to keep it under wraps.
The good old surfing principles of etiquette seem to be lost these days
